Generation 7 2000's to current
Roy Halladay...He will get in
CC Sabathia....He's got a decent shot but he looks like he's slowing down.
Felix Hernandez...It's still to early to say but he's got a good chance
Justin Verlander...Same boat as Felix Hernandez
Tim Hudson....This injury may cost him
Roy Oswalt....I don't think he has a chance
Cliff Lee...He's got a outside chance if he stays healthy
Bartolo Colon...Even with a steroid deduction he has no chance.
Barry Zito...No chance
Matt Cain...Possibly but he's geting lit up pretty hard this year.
Jake Peavy...Too injury prone
Chris Carpenter....Too many injuries
Dan Haren....No chance
John Lackey....No chance
Clayton Kershaw...Very good chance
Chris Sale...Staring out good
Adam Waignwright....starting out good
Zack Grienke...I would be surprised if he had a long career
AJ Burnett...I would say Buehrle is better
Andy Pettite..steroid deduction
Johan Santana...he has a good argument on being better than Buehrle but he looks like he's finished.
Cole Hamels....Possibly but I doubt he keeps it up.
Jered Weaver...He's looking strong.
Stephen Strasburg...Has potential
Matt Harvey....Might be injury prone.
Tim Lincecum...He'll probably be a reliever soon which may help his chances.

Mark Buehrle will have a top 8 career out of these guys.

Each generation will produce at least 8 Hall of Famer pitchers. I don't see too many of Mark Buehrle's generation having better overall careers than him.
